This open box is NOS. Famous free flight kit from 1950s by Midwest. A Ray Matthews design for 1/2A engines. Includes plan, covering tissue, balsa letter boards and other stock. May be missing parts. Please look at the pictures to see what is in the box. A nice Winter project to get away from Chinese Styrofoam ARFs and use your advanced aero-modeling skills. Will ship in box shown. Please ask any questions before bidding. Thanks.
